A cap is attached to the top of the collection bottle, and a connecting plate is attached to the outer side of the cap. The outer side of the connecting plate is fixedly connected to the inner side of the cabinet. A hinge is provided on the outer side of the cabinet. This portable water quality sampling device for environmental testing uses a first locking block to hold the collection bottle in place, an L-shaped plate to secure the battery, and closing the first and second door panels to store the device. Rotating the handle along the rotating shaft creates a carrying case, making it more convenient to carry.

[0004] The existing technical solutions have the following shortcomings: the existing portable environmental testing water quality sampling devices have a small sampling range and are inconvenient to adjust. In use, the above technical solutions use a water pump, a first water pipe, a filter head, and a second water pipe to work together to sample the water quality. However, this sampling device has certain limitations and is inconvenient to adjust the position of the water head, which limits the sampling range and results in poor applicability. Therefore, corresponding improvements are needed. Utility Model Content

[0005] The purpose of this invention is to provide a portable water sampling device for environmental testing, so as to solve the problems mentioned in the background art of the existing portable water sampling devices for environmental testing being inconvenient to adjust and having a limited sampling range.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a portable environmental testing water sampling device, comprising a fixed base and a support plate, wherein the support plate is disposed above the fixed base;

[0007] A sampling box is fixedly connected to the top of the support plate via a fixing block. A servo motor is installed inside the fixing seat, and a connecting rod is fixedly connected to the output shaft end of the servo motor. A drive gear is sleeved on the outside of the connecting rod, and a driven gear meshes with one side of the drive gear. A fixing rod passes through the inside of the driven gear, and the top of the fixing rod is fixedly connected to the bottom end of the support plate. A limit seat is fixed to one end of the top of the support plate, and a sampling test tube is movably connected inside the limit seat. A water pump is installed inside the sampling box, and a coarse filter box is fixedly connected to one side of the water pump via a connecting pipe. A water pumping pipe is fixedly connected to one side of the coarse filter box, and a drain pipe is fixedly connected to the other side of the water pump. A support frame is fixed to one side of the sampling box, and a rotating block is installed on the outside of the support frame. A rotating rod is fixed to one side of the rotating block, and a rotating gear is sleeved on the outside of the rotating rod. A movable toothed plate meshes with one side of the rotating gear, and a connecting block is fixed to the bottom of the movable toothed plate.

[0008] Preferably, one end of the water pump is fixed with a suction head, and a weight is sleeved on the outside of the suction head.

[0009] Preferably, a drain pipe is fixedly connected to the bottom of the drain pipe, and the drain pipe and the sampling tube are centered and aligned.

[0010] Preferably, a battery is provided on one side of the servo motor, and the battery is electrically connected to the servo motor via a wire.

[0011] Preferably, the limiting seat is provided with a uniformly arranged telescopic spring inside, and a limiting block is fixed on one side of the telescopic spring, and the sampling test tube is plugged with a sealing cap.

[0012] Preferably, the water pumping pipe is composed of a straight pipe and a corrugated pipe, and the coarse filter box is equipped with a large-diameter filter screen.

[0013] Preferably, support rods are fixed at both ends of the bottom of the support plate, and a limit groove is provided at the top of the fixing seat.

[0014] Preferably, the outer side of the rotating block is provided with a positioning pin, and the outer side of the support frame is uniformly provided with fixing holes.

[0015] Compared with the prior art, the beneficial effects of this utility model are: the portable environmental testing water sampling device makes it easy to adjust the position of the sampling head, expand the water sampling range, improve the applicability of the sampling device, and facilitate water sampling and testing, thus improving its convenience.

[0016] By rotating the rotating block, the rotating block drives the rotating rod to rotate, which in turn drives the rotating gear to rotate. This causes the rotating gear and the moving toothed plate to mesh, which in turn causes the moving toothed plate and the connecting block to move horizontally. Since the water pumping pipe is composed of both straight pipe and corrugated pipe, when the moving toothed plate and the connecting block move horizontally, they will drive the water pumping pipe and the suction head to move, making it easier to adjust the position of the suction head, expanding the sampling range of the suction head, improving the convenience of sampling, and thus improving the applicability of the water body sampling device for environmental monitoring.

[0017] By activating the servo motor, the servo motor drives the connecting rod to rotate, which in turn drives the drive gear to rotate. This causes the drive gear and the driven gear to mesh, which in turn drives the fixed rod to rotate. This allows the fixed rod to drive the support plate to rotate, and simultaneously allows the support rod to slide within the limiting groove. This facilitates the adjustment of the sampling device's position, making it easier to sample water quality in different environments and improving the convenience of water quality sampling and testing.

[0018] By setting a limiting seat, a telescopic spring, and a limiting block, the limiting seat initially fixes the sampling test tube. The sampling test tube is placed inside the limiting block, and the telescopic spring and the limiting block cooperate to limit the sampling test tube, thus fixing the sampling test tube inside the limiting seat. This makes it easy to limit and fix sampling test tubes of different thicknesses. Attached Figure Description

Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0027] Please see Figures 1-5 The present invention provides the following technical solution: Example 1

[0028] To address the inconvenience and difficulty in sampling water samples using existing environmental monitoring devices, the following solution is disclosed. Please refer to the details below. Figure 1 , Figure 4 , Figure 5 A portable environmental testing water sampling device includes a fixed base 1 and a support plate 2. The support plate 2 is arranged above the fixed base 1. A servo motor 4 is arranged inside the fixed base 1, and a connecting rod 5 is fixedly connected to the output shaft end of the servo motor 4. A drive gear 6 is sleeved on the outside of the connecting rod 5, and a driven gear 7 meshes with one side of the drive gear 6. A fixed rod 8 passes through the inside of the driven gear 7, and the top of the fixed rod 8 is fixedly connected to the bottom end of the support plate 2. A limit seat 9 is fixed to one end of the top of the support plate 2, and a sampling tube 10 is movably connected inside the limit seat 9. A battery is arranged on one side of the servo motor 4, and the battery and the servo motor 4 are electrically connected through wires. Telescopic springs 901 are evenly arranged inside the limit seat 9, and a limit block 902 is fixed to one side of the telescopic springs 901. A sealing cap is plugged on the sampling tube 10. Support rods 201 are fixed to both ends of the bottom of the support plate 2, and a limit groove 101 is provided on the top of the fixed base 1.

[0029] In this embodiment, during use, the servo motor 4 is started, causing the connecting rod 5 to rotate, which in turn causes the driving gear 6 to rotate. This meshes the driving gear 6 and the driven gear 7, which in turn causes the driven gear 7 to rotate the fixed rod 8. This allows the fixed rod 8 to rotate the support plate 2, and simultaneously allows the support rod 201 to slide within the limiting groove 101. This facilitates the adjustment of the sampling device's position, making it easier to sample water quality in different environments and improving the convenience of water quality sampling and testing. The limiting seat 9 initially fixes the sampling tube 10, placing it inside the limiting block 902. Utilizing the telescopic characteristics of the telescopic spring 901, the telescopic spring 901 and the limiting block 902 cooperate to limit the sampling tube 10, thus fixing it inside the limiting seat 9. This facilitates the limiting and fixing of sampling tubes 10 of different thicknesses, improving the adaptability of the limiting and fixing mechanism to a certain extent. Example 2

[0030] This embodiment differs from Embodiment 1 in that the sampling range of the sampling device can be adjusted by using the movable toothed plate 20 to facilitate sampling and detection. Therefore, the following technical solution is disclosed. Please refer to the following for details. Figure 1 , Figure 2 , Figure 3 A sampling box 3 is fixedly connected to the top of the support plate 2 via a fixing block. A water pump 11 is installed inside the sampling box 3, and a coarse filter box 12 is fixedly connected to one side of the water pump 11 via a connecting pipe. A water suction pipe 14 is fixedly connected to one side of the coarse filter box 12, and a drain pipe 13 is fixedly connected to the other side of the water pump 11. A support frame 16 is fixed to one side of the sampling box 3, and a rotating block 17 is installed on the outside of the support frame 16. A rotating rod 18 is fixed to one side of the rotating block 17, and a rotating gear 19 is sleeved on the outside of the rotating rod 18. One side of the rotating gear 19... A movable toothed plate 20 is engaged on the side, and a connecting block 21 is fixed at the bottom of the movable toothed plate 20. A suction head 15 is fixed at one end of the water suction pipe 14, and a heavy block 1501 is sleeved on the outside of the suction head 15. A drain pipe 1301 is fixedly connected to the bottom of the drain pipe 13, and the drain pipe 1301 and the sampling test tube 10 are centered and aligned. The water suction pipe 14 is composed of a straight pipe and a corrugated pipe. A large-diameter filter screen is installed inside the coarse filter box 12. A positioning pin is installed on the outside of the rotating block 17. Fixing holes are evenly arranged on the outside of the support frame 16.

[0031] In this embodiment, during use, by setting a weight block 1501, the suction head 15 is submerged in the water. The water pump 11 is started, causing the suction head 15 to draw water from different sources. The water is then transported to the coarse filter box 12 through the suction pipe 14. The coarse filter box 12 filters suspended debris such as plastic bags from the water to prevent clogging. The water pump 11, connecting pipe, and coarse filter box 12 work together to deliver the water source to the inside of the drain pipe 13. The sealing plug on the sampling test tube 10 is opened, and the water is then transported to the inside of the sampling test tube 10 through the drain pipe 1301 for water quality sampling and testing. The rotating block 17 is rotated, causing the rotating rod 18 to rotate, which in turn drives the rotating gear 19 to move forward. The rotation causes the rotating gear 19 and the moving toothed plate 20 to mesh, which in turn causes the moving toothed plate 20 and the connecting block 21 to move horizontally. Since the water suction pipe 14 is composed of a straight pipe and a corrugated pipe, when the moving toothed plate 20 and the connecting block 21 move horizontally, it will drive the water suction pipe 14 and the suction head 15 to move, which makes it easier to adjust the position of the suction head 15, expand the sampling range of the suction head 15, improve the convenience of sampling by the suction head 15, and thus improve the applicability of the environmental monitoring water body sampling device. Furthermore, by inserting the positioning pin on the rotating block 17 into the fixing hole provided on the support frame 16, the rotating block 17 is fixed, preventing the rotating block 17 from rotating and affecting the use of the sampling device.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
